Stock Watch for Top Drivers in NASCAR Sprint Cup Series

These are volatile times for fans involved in the business of following many of NASCAR's biggest stars in the Sprint Cup Series.

Time is money, and when you shake out how much time AND money many of this sport's most passionate fans pour into following their heroes, it's obviously the time to preach caution and prudence. Don't go out just yet and buy a new leather jacket with your longtime favorite driver's current car number on it. He might not be driving that car next year.

Furthermore, there might be better investments out there. Like a good stockbroker, fans need to take a long, hard look at their portfolios from time to time. Loyalty is one thing—and admirable. But there comes a time when a hard-line position needs to be evaluated, and perhaps, adjusted.

Click ahead to find out which Sprint Cup drivers deserve to have stock in them bought, sold or held until further notice.
